Is Italian salad dressing a solution or mixture?

Here's why:

* Solutions are homogeneous mixtures where one substance (the solute) dissolves completely into another (the solvent). The result is a single, uniform phase.

* Mixtures are combinations of substances where the individual components retain their own properties. They can be homogeneous (uniform throughout, like salt water) or heterogeneous (non-uniform, like sand and water).

Italian salad dressing contains several ingredients like oil, vinegar, herbs, and spices. These ingredients don't dissolve completely into each other. They form a heterogeneous mixture with visible components and distinct properties.

Think about the separation of oil and vinegar in the dressing - that's a clear sign it's a mixture!
